Co2-Based Demand-Controlled Ventilation (2005)

APP-CMC024-EN

The mobility of a building's occupants poses a ventilation challenge to bring enough outdoor air into the building to help assure good indoor air quality without wasting energy by bringing in (and conditioning) too much. This ENL discusses the use of carbon-dioxide (CO2) sensors to vary outdoor airflow based on actual demand. It also considers the related requirements for compliance with ASHRAE Standard 62.1-2004.
